BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a polyester fiber and lightweight wovennylon yarn blended process, and more particularly to a polyester fiberand lightweight woven nylon yarn blended process by which twolightweight processes in weaving procedures are employed to produce afabric with lighter weight.

2. Related Art

China patent publication number CN100558978C titled “Microfibers DyeingMethod and Fabric Woven from the Dyed Microfibers” dated in 11 Nov. 2009comprises a lightweight procedure, in which the microfibers are windedon a yarn dyeing machine, an alkaline reagent is added to the windedmicrofibers under an even temperature between 100 to 130° C., andmaintained from 30 to 60 minutes to reduce the weight of the microfibersby 6 to 15%; a water rinse procedure, in which 70 to 80° C. nonferrouswater is sprayed into the lightweight microfibers by a spray nozzle toeliminate impurities from the microfibers by water pressure, a cleaningagent is used for cleaning the microfibers, and the microfibers areundergone an acidic treatment to reach a PH value of 4 to 5; a waterrinse procedure; and a water rinse and drying procedure.

The above conventional method uses the corrosive alkaline reagent toreduce the weight first, and the acidic treatment is further employed tobalance the acidic and alkaline values. The discharging of the alkalineand acidic agents will cause environmental pollution and therefore doesnot conform to the environmental standards, which is one of thedisadvantages.

Furthermore, the use of the corrosive alkaline reagent to reduce theweight first, and further the acidic treatment to balance the acidic andalkaline values is not only troublesome in operation, but will alsoincrease the cost of work time. Additionally, the alkaline reagent andthe acidic reagent used for balancing will increase the cost ofconsumables and therefore does not conform to the economicaleffectiveness, which is another one of the disadvantages.

Lastly, the finished product produced employing the above troublesomeoperation is merely yarn, which only belongs to the preliminaryprocedure in producing a fabric as the finished product. The absence offabric as the finished product further exposes the disadvantages of timeand work consuming and troublesome.

SUMMARY OF THE INVENTION

The present invention of a polyester fiber and lightweight woven nylonyarn blended process aims to solve the drawbacks of the conventionalmethod mentioned above, which are environmental pollution caused by theuse of the alkaline agent and the balancing acidic agent, and theincrease of costs caused by troublesome in the preliminary procedures inproducing a fabric, and yet cannot obtain the fabric as the finishedproduct.

A primary objective of the present invention is to provide a polyesterfiber and lightweight woven nylon yarn blended process which does notrequire the use of the alkaline agent and the balancing acidic agent inorder to avoid environmental pollution.

A secondary objective of the present invention is to provide a polyesterfiber and lightweight woven nylon yarn blended process which does notrequire the troublesome operation in using corrosive alkaline reagentand the acidic treatment for balancing afterwards, and therefore canreduce the costs and is economically effective.

A third objective of the present invention is to provide a polyesterfiber and lightweight woven nylon yarn blended process which does notrequire troublesome preliminary procedures and can still produce afabric with a lighter weight as the finished product directly throughprocessing lightweight procedures two times.

The present invention of a polyester fiber and lightweight woven nylonyarn blended process comprises following procedures of:

a lightweight weaving procedure A, in which a plurality of chemicalmonofilament fibers is twirled into bunched chemical monofilament fibersby a kneading process, the bunched chemical monofilament fibers and awoven complex yam (polyester fiber and woven nylon yarn) are fed into ayarn entrance of a loom simultaneously, the loom is equipped with afiber opening knife for performing a fiber opening process for the wovencomplex yarn, the fiber opening knife performs the fiber opening processto cut the woven complex yarn into a plurality of equal sized furcalstructures longitudinally to cause wear and tear to achieve lightweightpreliminarily, then the furcal structures and the bunched chemicalmonofilament fibers are undergone a knitting process to obtain alightweight fabric;

a secondary lightweight procedure B, in which the lightweight fabricwoven using the previous procedure is washed with 130° C. water to causefurther partial damage to the nylon in the woven complex yarn of thelightweight fabric by the water temperature 10° C. higher than thetemperature (not over 120° C.) that the nylon can endure in order toachieve lightweight the second time;

a dyeing procedure C, in which a dye, a dispersant agent, a levelingagent, an antistatic agent and a softening agent are added together fordyeing the lightweight fabric under pressure; and

a water rinsing and drying procedure D, in which the dyed lightweightfabric is washed with water and dried for obtaining the finished productof the present invention.

The bunched chemical monofilament fibers are kneaded from the chemicalmonofilament fibers to have a thickness of 150 to 500 deniers.

The chemical monofilament fibers are selected from polypropylenechemical monofilament fiber, nylon chemical monofilament fiber, orpolyester chemical monofilament fiber.

The woven complex yarn has a thickness of 50 to 320 deniers.

The present invention will become more fully understood by reference tothe following detailed description thereof when read in conjunction withthe attached drawings.
